Meet the Ophthalmic Pathology team of physicians
José M. Bonnin, MD
CLINICAL PROFESSOR; DIRECTOR, NEUROPATHOLOGY FELLOWSHIP PROGRAM
Education: MD National University of Asuncion, Paraguay; Resident in Pathology, Danbury Hospital; Fellow in Neuropathology, University of Virginia
Board Certification: Diplomate of the American Board of Pathology in Anatomic and Clinical Pathology
Subspecialty Certification: Neuropathology
Special Interest: Neuropathology and Ophthalmic pathology
Address: Indiana University Health Pathology Laboratory
350 West 11th St., Room 4038
Indianapolis, IN 46202-4108
Expeditious Turn Around Time
- 24-hours for most ophthalmic specimens (unless special studies are necessary for diagnosis)
- Same-day interpretation on slide consultations
- Five working days for enucleation and exenteration specimen
- A confirmation is faxed upon receipt of the specimen identifying the pathologist interpreting the case and providing contact numbers.
- The pathologist contacts the submitting physician when the biopsy findings require discussion. A faxed final report will follow.
- The pathology outreach coordinator makes regular contact with your office to ensure quality of service.
Specimen Preparation and Transportation
- Complete the requisition form and fax the form and the patient's demographic information to 317-491-6419 before sending the biopsy.
- Place the specimen in the proper fixative (indicated below) and transport in a leak-proof hard plastic container placed in a zip-lock bag along with the submission form and all accompanying information, including the most recent clinical information.
- Place all in a box or mailing tube filled with packing materials (paper towels, etc.)
- Autopsy eye, ciliary body, conjunctiva, enucleation, evisceration, exenteration, eyelid, iris, lacrimal system, muscle, optic nerve, pterygium, skin, trabecular meshwork, temporal artery biopsy: 10 percent neutral bufferd formalin
- Corneal Buttons: Formalin is not a universal fixative for corneal tissue. Please call 800.433.0740 before surgery when the anticipatited diagnosis will require the following:
- electron microscopy
- immunofluorescence or
- the detection of crystalline substances, as fixation depends of the type of test required
- Foreign Body: Please call 1.800.433.0740 before sending.
- Slide and Block Consultation: Place slides in a plastic slide mailer - do not send in a flat cardboard or plastic mailer.
- Special Procedure Specimen Collection - Call 800.433.0740 prior to surgery.
- Corneal Scrapings for Acanthamoeba: Transport in Saccomanno fixative
- Electron Microscopy: Transport half of the specimen in 2.5 percent glutaraldehyde and half in 10 percent neutral buffered formalin.
- Fine Needle Aspiration and Vitreous (intraocular biopsy, fluid and eye tissue fragments): Transport in an equal amount of Saccomanno fixative.
- Immunohistochemistry and Metabolic Diseases (gout, cystinosis, storage disease) - Call for specific instructions.
